Electrochemical Direct Synthesis of N-Sulfenylimines from Amines in the Presence of Thiophenols.

N-Sulfenylimines are important molecules owing to their value in organic synthesis. Herein, we developed an electrochemical oxidative cross-coupling reaction between amines and thiols to synthesize N-sulfenylimines without a transition-metal catalyst and external oxidant. Various amines and thiols were compatible, generating the desired products in up to 86% yield.
